Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

Meteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Reaffirming the Consistency of the Original Stock of NBS 19 Limestone and Its Byproduct With Finer Grain Size for δ¹³C and δ¹⁸O Calibrations-Both Distributed Internationally. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Approximately 3–4 kg of NBS 19 limestone, prepared in 1982 by the U.S. Geological Survey (USGS), serves as a primary reference for the carbon isotope scales VPDB and VPDB‐LSVEC and the oxygen isotope scale VPDB. Its consensus values are +1.95‰ for δ13C and −2.2‰ for δ18O measurements.

Diversity and Plasticity of Hydraulic Traits Across a Relative Moisture Supply Gradient: Results From Multiple Common Gardens

Plant, Cell &Environment, EarlyView.
ABSTRACT Maintaining cellular hydration is essential for plant metabolic activity and carbon gain. Plants typically maintain hydration through efficiency of water transport networks, the ability to avoid network disruption, and retention of water via accumulation of osmotica. Given their global domain and their enduring presence across geological eras,

CrustCheck: a conceptual framework for interpreting biocrust trait–function relationships in drylands

Restoration Ecology, EarlyView.
Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Climate benefits of wetland restoration are constrained by slow vegetation recovery

Restoration Ecology, EarlyView.
Abstract Introduction Wetland restoration is widely used to enhance ecosystem resilience, biodiversity, and climate mitigation. However, restoring hydrology may not lead to rapid vegetation establishment or reduced greenhouse gas (GHG) emissions in severely degraded wetlands.
